It operates on media items in Umbraco CMS by updating properties. The severity is medium because unintended updates to media metadata could cause operational issues or corrupt asset references, but the impact is limited to individual media items and is reversible. From the tool's own definition: "Tool name is 'update-media' and description states it 'Updates a media item by Id' — a reversible modification operation." ## Use case AI agents use update-media to create or update resources in Mcp Dev, usually the action step of a workflow, after the agent has gathered context.
